BIG SUR problems with SMB

I had switched to SMB and it was working ok, then AFP dropped my connection one day while transferring files.. . So I forced my Qnap BACK to to only do SMB 3.0, since this is what Apple recommends.

It seemed to work fine at first, then I got dropped again the other day, randomly.. I have noticed, UNZIP, LARGE FILE TRANSFERS and RENDERING will all randomly drop with SMB. AFP sometimes for big renders but not as often..

AFP drops less.
AFP is a little slower, less snappy.

SMB drops more often.
SMB is faster

Anyway, it is frustrating as all "H E double hockey sticks"
Wish I knew a solution.

The only thing I could really do is try to connect with Windows and or Linux and do the same types of transfers and see if it is truly a MacOS thing.

I am getting the impression that the DS_Store files and other invisibles are a bigger problem than I thought. I have been a mac tech for over 20 years and have worked for Apple in a technical capacity. I have only been using a NAS for a few years but have seen some wild situations on my own several NAS's and others that can be traced back to these invisibles that I always thought were rather benign. Not so, and especially not so on SMB. I found this great app to remove them on the Mac App store called BlueHarvest. Its fast and efficient and gets the job done. Id look in to that.
 
My issue is similar, regarding this SMB with Big Sur. But I wonder if it's compounded with M1 processors?

We've got an M1 Mac mini, with 16GB Ram, currently running the latest 11.4 build. Issue has been persistent since initially setting this up back in January. SMB shares are what our files live by. We have a full array of 6 different SMB shares on our internal network, that contain all of our working and archive files for various client data.

Our issue isn't with connecting, but staying connected. The servers never seem to show disconnected. But working on live files causes the apparent temporary disconnects during big file transfers, working on open files, or even browsing through the file structure on the shares.

We have InDesign, Photoshop and Acrobat files that we work with intensely. And it appears that while working on a server base InDesign file, it'll just hang and Finder, Adobe apps, and QuickLook Specifically just stop responding. Requiring force quoting all of those processes. And then once Finder reloads, we're back up. Though any unsaved work must be recovered or redone. So I've been saving constantly the past few months.

I thought it may be due to the Rosetta emulation of most adobe products. Though Photoshop is now M1 native. But even browsing through files on the server, in column view, appears to trigger the hang the most. Example would be jumping into a folder, then selecting a pdf that then attempt to quicklook draw the thumbnail in the following column, then beachball. Though if I'm in List view, this doesn't happen. Or potentially not right away, as potentially opening the PDF in Acrobat Pro, or a psd or indesign file, may crash it as well.

I've tried changing all of the shares to AFP, to no help. But now, as of today, per some of the ideas here, deleted and reconnected and favorites all the shares as smb://(username)*@share and turned off spotlight search on all of those connected drives. Not that any Finder search in the shares ever found anything anyway.

Thoughts, experiences, resolutions or workarounds anyone?

I tested on my i7 iMac and my M1 MacbookPro, but honestly the MacBook Pro M1 seems more stable.

My SMB is connected over 10gE on a Qnap. A few things I started doing.

-- Never let finder connect directly to the server, I only connect to my Qnap with the Qfinder and I never save any passwords via finder. Use your network tools to connect, never directly.

-- Disabled all hidden folders on the network and got a hidden folder cleaner called BlueHarvest. I had to scrub my network drives which too forever. It also is supposed to prevent MacOS from writing any hidden folders to the network.

This has not 100% fixed the problem but it is a little more stable.

After upgrading to Big Sur, SMB is not working as before.

I have a Windows machine with about 20 shared folders. In the past, I simply used Control-K, then SMB://192.168.50.228 (windows IP)

AFter that it would reach that machine. I would be presented with all of the shared folders available. I would highlight any or all of them and hit Connect. Then they would all appear for use.

Now, if I try this, it eventually times out. I must connect to each folder individually. Example: SMB://192.168.50.228/Work Documents

Then it will connect to that folder.

I want it to work the way it was before. What is going on here?

Hi All, I have the exact same issue with my new M1 MAX MacBook Pro. I am tyrying to connect from my 2020 iPad pro to my New Mac via the FileBrowser app. Thank You, for the work around and it does work. I can connect to my Mac if and only if I specify the exact folder I want to access. Otherwise it just times out. I am on Monterey 15.1, I believe.
 
It sounds like many of you have issues on the server-side of the equation. Specifically allowing each discreet share (export) to be browseable (or "advertised"). It's possible your SMB servers aren't set up for down-level mapping too.

Thank you for commenting! Its clear you know more about SMB than we do (being totally serious) and if you go further through the
 
I would also say, if anybody is still reading this thread, that SMB 3.1.1 in Monterey seems quite good even though Ive only been using it a few days. Speed is awesome and no hangs. Anybody else?

After updating from Big Sure to Monterey maybe was broken license key or had changed the SMB version
therefore
1) Go to Setting and disable share files
2) You should be waiting for ~ 10 minutes
3) Restart MacBook
4) Enable share files again. Mac OS renew(index) folders
5) Use your smb share folders well

I think this way will be well another MacBooks.

Best wishes, bye.))
 
Hello, late to the conversation but I am checking here for some time now.
Using and old (2016) Synology here with some Mac mini M1. Many kind of files, audio, video and mostly InDesign, Photoshop etc.
My main issue is that described above many times. While working with Photoshop (2021 or 2022) on Big Sur on the M1 Mac mini I cannot replace the psd file on the network for example.
I open the file from the NAS to Photoshop and doing some changes (change font, add background, layers reorder etc doesn't matter actually). When I am finishing with that file and I want to save the changes I am always getting one of the below errors.
Could not save "file.psd" because of a program error
Could not save cause file is empty.
Could not save cause of disk error

What is worth to mention is that I have tried to enable NFS and work with that.. too bad no labels or tags can be used with NFS.

Another issues that appear from time to time is that I might wait for minutes for InDesign to save a file or that InDesign crashes during the process.

Please share your experience if you have similar. I've installed BlueHarvest today to test it out by removing those DSStore files but the thing is what it is. I can't do anything else. TIA :)

I have no experience with Synology, so perhaps this is not even an option, but have you tried AFP?

It is a pretty outdated ****** protocol but at least labels and tags work if that is important.
 
Thank you for your reply! Let's hope that DSM update released for Synology will squash the issues... AFP is dead suddenly.. even Apple says don't use it :)
